Limiting Reactant Calculation Question
In one of the post-module assessment problems, I was asked to find the theoretical yield of a product using the limiting reactant and molar ratios. I found the limiting reactant to be 1.56 mols and the reactant–product molar ratio to be 4:5, so what would the next step be? Do I just multiply the 1.56 mols by 5?

You would multiply the 1.56 mol reactant by 4 mol product/5 mol reactant. This uses stoichiometry to convert the moles of reactant into moles of product.

Another way to approach this is using dimensional analysis:
You have 1.56 mol reactant and you want to convert to mols of product, so multiply 1.56 mol reactant times (5 mol product/4 mol reactant). I think the last answer just got the 4:5 ratio flip flopped.
